FIREARM.

Application filed September 27, 1921. Serial No. 503,573.

To all whom it may concern:

Be it known that I, ELLISON D. HENRY, a citizen of the United States, residing at Houston, in the county of Harris and State of Texas, have invented certain new and useful Improvements in Firearms, of which the following is a specification.

This invention relates to new and useful improvements in a fire arm, and has particular relation to the magazine of said arm.

One object of the invention is to provide an improved form of magazine which is particularly useful in connection with an automatic gun, said magazine having a removable extension which, when in use, will increase the capacity of the ordinary magazine in common use on automatic guns.

Another object of the invention is to provide an extension for a gun magazine which may be cheaply and easily constructed and readily applied or removed.

With the above and other objects in view this invention has particular relation to certain novel features of construction, operation and arrangement of parts, an example of which is given in this specification and illustrated in the accompanying drawings, wherein Figure 1 shows a side view of the gun with the extension applied to the magazine thereof.

Figure 2 shows an enlarged fragmentary longitudinal sectional view of a gun showing said extension applied thereto.

Figure 3 shows an enlarged fragmentary side view of a gun showing the ordinary form of magazine, without the extension applied, and

Figure at shows a cross sectional view of a gun taken on the line i-d of Figure 1.

Referring more particularly to the drawings, the numeral 1 designates the stock of the gun, the numeral 2 designates the barrel thereof, and the numeral 3 refers to the magazine. The magazine 3 has the recoil spring 4 therearound to receive the recoil of the gun after firing. The outer end of the magazine 3 is closed by the cap 5 which is screwed thereon. The parts above referred to are of conventional form and common to guns of this character.

The numeral 6 designates a tubular extension of the same diameter as the magazine 3.

The outer end of this extension is closed by the cap 7 and its other end is internally threaded.

In Order to apply the extension the cap 5 is first removed and the threaded end of the extension 6 is then screwed onto the threaded outer end of the magazine 3. The extension is clamped to the gun barrel by means of the clamp 7.

The cartridges 9 are inserted into the magazine, in the usual way and rest against the coil spring 10 in the magazine. This spring should be some what longer, when the extension is used, than when the ordinary magazine is used without it. The spring acts in the usual way and its function is well understood by those familiar with the operation of guns of this type.

It is obvious that a greater number of cartridges may be carried by the magazine when the extension is employed, and when it is not required it may be removed easily, and readily carried about for use when occasion demands its use.

What I claim is The combination with a gun having a tubular magazine for the reception of cartridges whose outer end is externally thread ed of a tubular extension whose inside diameter is the same as the inside diameter of the casing, and one end of which is internally threaded and screwed into the externally threaded end of said magazine, a cap threaded into the other end of said extension, a clamp surrounding said extension and whose upper end is formed with arcuate fingers which embrace the gun barrel, a set screw threaded through the clamp between said barrel and the extension, and a single coil spring whose outer end rests against said cap and against the cartridges in the magazine and extension.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

ELLISON D. HENRY.
